THERMAL DECOMPOSITION OF 2,2-DIFLUOROPROPIONYL PEROXIDE IN HYDROCARBON SOLVENTS

The thermal decomposition of 2,2-difluoropropionyl peroxide in heptane is a monomolecular process with a rate constant of 1.1E13 expsec-1.The main gaseous products from the decomposition of the peroxide in heptane and isooctane are 1,1-difluoroethane, 1,1-difluoroethylene, and 2,2,3,3-tetrafluorobutane.The CH3CF2. radicals generated in this process take part in the abstraction of hydrogen atoms from the solvent, disproportionation, and recombination.The decomposition of the peroxide at low initial concentrations in heptane can be used as a method for the generation of CH3CF2. radicals for kinetic investigations.
